Figure 4 is a of such size and width as to permit the end front elevation thereof. of the lever bearing the head 29 to be readily In the drawings there is shown a gas presinserted therethrough and hooked over the sure regulator of the usual form having a lower knife edge 30 so as to normally bear s5 trap frame in two sections, the upper section thereupon. The opposite end of the lever extion is provided with a depression 12 forming with an adjustable valve stem screw 32, said a laterally extending channel 13, which terscrew being adjustable therethrough and exminates in a valve housing 14. Said sections tending downwardly therefrom immediately 90 are provided with abutting flanges which over a reduced passage 33 communicating may be secured together by the usual bolts with the chamber of the valve housing and. so as to completely encase the operating the fluid intake 23.-

mechanism. The valve stem screw 32 is provided on vided a leather diaphragm 15 having an 34-into which the rounded head 35 of a disk upper metallic plate 16 covering the greater valve 36 is adapted to seat when said valve ortion of the area thereof, said plate 16 beis placed in position.) The; head 35 of'the ing rigidly secured to the lower plate 17 by a valve is joined thereto by a flattened neck screw 18,whereby the leather diaphragm will portion 37 adapted to be slldably engaged 100 15 movement with respect to the lever so as to against the diaphragm 15. The end of the 10 and the lower section 11. Said lower sectends into the valve. housing and is provided f 45 Secured between the flanges there is prothe lower end thereof with a socket or recess between the spacedspring-like arms 38 of a ing the plate therein,

spring metal bracket 39. Said bracket is mounted inposition on the end of the lever 26 by loosely mounting the upper portion thereof over anupwardly extending pin 40 so as to permit it to have vertical movement with respect thereto without becoming disengaged therefrom. The lower rearward end of the bracket extends. under the forward portion of the head of the lever 26 and is rigidly secured to a shoulder thereof. This permits of a spring movement of said bracket in a vertical plane. The bracket is provided in its front face with an enlarged opening 40 adapted to receive the head 35 of the valve, said valve being held in position within the bracket by the engagement against the flattened portions of its neck 37 by arms 38. Upon the screw 32 being adjusted to'engaging position, the head 35 will be embraced by the socket or recess 34 formed in the lower end thereof so as to normally maintain the valve in position and prevent it from moving out of engagement with the bracket.

Access to the valve may be had by remov- 25, whereupon the removal or replacementof the valve may be had by grasping the same by a pair of pliers or the like .and forcibly moving it longitudinally, so that its head 35 may be engaged with or disengaged from the recess or socket 34 of the screw 32 upon the spring tension of the bracket 39 being overcome. In the spring tension of the bracket 39 has the effect of normally maintaining the head'35 of the valve in engagement with the socket 34 under spring tension, but permitting its forcible removal therefrom.
